Over wintering Coleus question

Last year I was giving 2 Coleus plants that did not fair very well being kept as indoor house plants. After taking some cuttings and getting them to root, I have potted them and kept outdoors this summer and they have really flourished and are doing well. 
I do not have a green house that I can store them in over the winter but really do not want to lose them. I have taken a couple of cuttings to start new plants but was wondering if anyone had any ideas how I might be able to protect them during the cold months.
I was thinking of trying to cover with clear bin bags to try to keep the frost off. Do you think this will work?? Any ideas or suggestions would be appreciated. 
I live in lincolnshire in the UK if that helps. Thanks in advance.

    I don't think they will survive outside no matter what you do. Have you got a porch?

  • The best way is to take them indoors. Coleus will not like frost. If you try them outdoors, a sheltered spot where they get light might work and your plastic bag idea. If you cover them with plastic let the air get in and don't forget to water. Personally I would keep them indoors in somewhere light
  • Take lots more cuttings (in a jar of water) and resign yourself to losing the parent plant.  They never look as good the second year anyway ... they get leggy.

  • Thanks for the advise. Think I will take plenty of cuttings and try to shelter parent plants and see what happens next year.

    I think the advice given above is good.
    I've been growing coleus from seed on and off for 50+ yrs.
    They will have no chance whatsoever outside, even if you manage to keep them frost-free. They're just too full of water and will freeze or rot at the first opportunity.
    If you do keep the parent plants inside over winter, they may survive, but I have found soon as spring arrives, they look tatty, start to form flower buds, then die.
    You best bet is to follow the advice given above by Dove (ooh - that's almost an anagram!) :)
